TESTIMONIALS

** HIGHLY RECOMMENDED** I wish I could give them more than 5 stars. Second order from them and just as impressive, if not more! I super appreciate the additional ones since they are so tiny! It fits perfectly!! Thank you so much!

Excuse my messy work space but I LOVE THE UPGRADE KIT! My true 32 sits straight as a board!! Pro tip! If u don't want to drill into your counter just lay down some metal sheets and attach magnets to the kit. Works like a dream! I like to move my turner's as I work because my space isn't big enough so this allows them to be able to be moved but not tip over! I will be buying another kit soon to upgrade my 3rd spin it!

Absolutely love their cup inserts. They have the perfect sizes for what I need and are always ready to help with the questions I have. I would recommend them to anyone who makes cups! Slowly fading out my footballs with their inserts and I can’t wait to order more.
